Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19470, here are decompositions:

  • 7 + 19463 = 19470
  • 13 + 19457 = 19470
  • 23 + 19447 = 19470
  • 29 + 19441 = 19470
  • 37 + 19433 = 19470
  • 41 + 19429 = 19470
  • 43 + 19427 = 19470
  • 47 + 19423 = 19470

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19470 first appears in π at position 116,949 of the decimal expansion (the 116,949ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
